Question

на провідник довжиною 80 см, що міститься в магнітному полі під кутом 30° до силових ліній, діє сила 5Н коли по провіднику проходить струм 5А. визначити магнітну індукцію

Answer 1

Ответ:

2,5 Тл

Объяснение:

L=0.8 м    α=30°    F=5 H    I=5 A     B=?

===

F=I*B*L*sinα

B=F/(I*L*sinα)=5/(5*0.8*0.5)=2.5 Тл

Answer 2

Calculation of Magnetic Induction

To determine the magnetic induction (B) in a conductor, we can use the formula:

B = (F / (I * L * sinθ))

Where: - B is the magnetic induction - F is the force acting on the conductor - I is the current flowing through the conductor - L is the length of the conductor - θ is the angle between the conductor and the magnetic field lines

Given the following values: - Length of the conductor (L) = 80 cm = 0.8 m - Angle (θ) = 30° - Force (F) = 5 N - Current (I) = 5 A

Substituting these values into the formula, we get:

B = (5 N / (5 A * 0.8 m * sin30°))

To calculate the value of sin30°, we can use the trigonometric identity:

sin30° = 0.5

Substituting this value into the formula, we have:

B = (5 N / (5 A * 0.8 m * 0.5))

Simplifying further, we get:

B = (5 N / (2 A * 0.8 m))

B = 3.125 T

Therefore, the magnetic induction in the conductor is 3.125 Tesla.
